The amount of explosives taken this past weekend from a Lancaster County drilling worksite is even greater than initially reported, according to new information from the Bureau of Alcohol, Tobacco, Firearms and Explosives.

The ATF reported Wednesday afternoon that it was determined 704 pounds of explosives were taken over the weekend from Gregory General Contracting Co. in Marietta.

The ATF is offering a $10,000 reward for information that leads to the recovery of the explosives and/or the arrest and conviction of those responsible, a news release stated.

The stolen explosives had been stored inside a locked, truck trailer which was left on site at Gregory General Contacting after workers left on Friday, April 13. The worksite security company did not discover the theft until Monday, after noticing that the trailer door was ajar with the locks missing, the release stated.

“The ATF, along with our law enforcement partners are committed to ensuring that our communities are safe and that those who violate federal explosive laws are held accountable," said Donald Robinson, Special Agent in Charge in the release. “We are asking for the public’s help in our effort to apprehend and convict those responsible.”

Theft and possession of stolen explosives is a federal crime that is punishable by up to 10 years in prison.
